No. 22936/20; and I do hereby declare the following to be a clear, full, and exact description' of the invention, such as will enable others-skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, and to lettersy or figures of referencemarked thereon, which form a part of this specification. i

The invention relates to improvements in f a device for fixing yand actuating sliding f ting out of order.

windows particularlylon vehicles, wherein, in a known manner, by means of a folding lever which is rigidly connected to its axle of rotation the linkage for actuating the windows canbe displaced as well as the lateral rods can be shifted. e y y VThe known sliding windows of vthis type Vprovided with such a device 'are either fitted with special upper and lower frames which have to be disengaged first bythe lateral rods in order to be able to shift the window, or the sliding windows are provided withl a. special upper `guidancewhich secures thev window inthe top-most position. V

' Besides the fhigh costs these 'slidingrwindows present the disadvantage that their construction is very complicatedlon'v account of'these special pressure frames and'further they are.subjectedV to lamming and to getwith upper guidance cannot be applied to vehicles with folding hoods-and' can only bedisplaced when mounted in ka vertical position `andl not inA a, more or less oblique position. v 7

YThe object of the f present. invention is to improve the known constructions so that the hitherto existing disadvantages of these slidingwindowsare overcome in dispensing with the separate pressure frames and with the upper guidance andyet'enabling :a re-v Specicaton of Letters Patent.

axle of the actuating mechanism, with its one end in an articulated manner to a lever that can be folded so that when said lever is .folded a sliding member with a beveled end 1s pulled along a slot provided in the aXle, whereby a bushing being displaceably arranged surrounding vthe axle and provided on its outside with a lug in the shape of an inverted V is pushed against the action of a compression spring toward the outside, upon which displacing motion said lug co-acts with two members turnably mounted on two pivots pressing them apart and simultaneously causing the lateral rods with their beveled ends to be pressed against the clamping members that co-act with the window so that the window is fixed, in position, while on the other hand when the lever is unfolded the sliding member is displaced'relatively to the slot in the axle and the bushing glides toward the inner side upon the action of the spring, the lug is withdrawn from said members whereupon the latter are again closed by the lateral rods which are influenced by springs so that the window may be moved up or down as the clamping jaws disengage the latter.

Thedaccompanying drawing shows in a diagrammatic manner an exemplification of the invention in, which:

Figure 1 is a. window arranged .in the door of a vehicle and seen from the inside; Fig. 2 is a vertical section of Fig. 1, some parts being omitted;

transmits the turning motion to a dislr g rigidly connected to it. rThis disk acts as a crank for the connecting link 7L and its turning motion is limited by the stops t and 5 which abut against the connecting link and prevent too great a turning motion of the system. The motion is transmitted by the connecting link t to a pivoted lever c', which is turned in the direction of the arrow shown in Fig. l and which displaces the bell crank lever Z by means of the link 7c. To the lower end of the bell crank lever Z a roller m is providedy which rolls along guides a fitted. to a frame in the lower part of the window. in consequence of the pressure excrted by the lever Z the window 7) is shifted upward or downward according to the direction in which the handle is turned. ln order to damp the downward movement of the window a spring loaded buffer rod 0 is interposed between the lever i and the lower edge a of the door frame. When the lever z' moves downward the spring is compressed Y and takes up any eventual shocks so that the window Z9 can never fall against the frame even if the handle is let go.

The fixing of the window ZJ in any desired position is carried out by means of the handle c anc. a pair of lateral rods o operatively connected to it. For this purpose the handle e consists of a lower part 2 rigidly connected to the axle 7 and the upper 3 articulated to the lower part and adapted to be folded on to it, in this way the handle part is lengthened into a lever and the whole mechanism may be worked very easily. rllhe axle is surrounded by a bushing p which is provided at one side with a lug g that has the shape of an inverted V, the bushing being pressed toward the outer side, (i. e. toward the handle e) by means of a spring r. The axle f is provided with a slotinl which a sliding. member s fitted with an enlarged end slides. The sliding member 's has a vertical slot- 6 provided at one end into'which a gliding pivot e of the upper part of the handle is inserted. To the inner side of the wall of the door which carries the whole device and toward the window b the members t arerotatably mounted around pivots y. Against these members 25 the rods e abut, which rods are pressed against the latter by the plate springs vrw, the

rods o are fitted with beveled ends a2 which co-act with the beveled clamping parts CZ.

rlhe described device is operated as follows: If the upper part 3 of the handle e is folded on to the lower part 2 the sliding member s together with its enlarged end is pulled through the slot of the axle f so far that the bushing p is pushed toward the outside overcoming thereby the pressure of the spring fr and the lug g presses apart the two members t turning' them around the pivots y. rl`he members r3 push the rods e against the pressure of the springs w in an outward direction. The wedge shaped ends of the rods o press the beveled clamping members d toward the window in such a way that the latter' is held firmly in any given height or position.

In order to shift the window the upper part 3 of the handle e is unfolded, whereby the sliding member s with its enlarged end is pushed along the slot of the axle f and the bush p glides through the action of the pressure of the spring r toward the inner side, the lug g disengages the members t whereupon they are pushed against each other Vby the action of the plate springs w and the interposed rods o. The wedgeshaped ends .r of the rods o disengage the beveled clamping members (Z. The latter are, through the action of the springs fw, removed from the window and disengage the latter so that the window can at will be raised or lowered by turning the handle part.

ln order to iix the window again the upper part 3 of the handle e has only to be folded. The frame of the window is provided at its right and left hand side with extended parts l which insure a reliable fixing of the window and an effective guidance when it is raised by its full height.

This construction insures a safe working of the mechanism without any shoclrs occurring and a perfectly safe xing of the window in any desired position. The latter is effectively guided up to its highest position and no upper guidance is required, so that for instance a vehicle without a cover can be closed in around its whole circumference by such windows without materially hindering the view. This construction enables further to, use such a window with open vehicles fitted with half doors. No straps, ropes, wires, cords, toothed wheels or other means to wear out quickly are utilized. The displacement of the window is easy, simple and requires no special exertion of strength. Any jamming or clattering of the window is excluded and the latter moves in a gentle way when being shifted.
